Left 4 Dead sells 2.5m copies in retail
Valve’s co-op survival horror action shooter has sold 2.5 million units at retail, project lead Michael Booth revealed today at GDC.
The sales come from both PC and Xbox 360 sales at retail, but not from Steam. Considering the popularity of Left 4 Dead on Steam, it’s fair to assume that the game has sold 3 million copies in total, making it one of Valve’s best sellers, only surpassed by Half Life and Half Life 2.
